The supplier rejected including PPA, but declined to expose what had been contributed to the binder. When pushed by the division of transportation, the supplier revealed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB has a percentage of phosphorus, which is what department drug stores at first identified.


"No person understood this material was being included in asphalt, had seen any kind of research on how this might impact performance of hot-mix asphalt pavements, or knew for just how long and just how widely it was being used throughout the country," claims Mueller. After conversations at the technical conference, he states, "It promptly went from being simply an issue in Illinois to ending up being a national and global issue."

A device called a vibrant shear rheometer (DSR) was presented to the industry throughout the Strategic Freeway Research study Program's research job, which ranged from 1987 to 1992. The DSR is currently the sector standard for measuring the viscoelastic homes of paving asphalt. Nevertheless, the machine was not established for the paving market.


As an example, the DSR enables product designers to create toothpaste with the best consistency so that it can be pressed from a tube however not fall off the tooth brush. The DSR examinations binder placed between two identical plates about the dimension of a quarter. Among home plates steps and the machine determines the viscoelastic residential or commercial properties of the asphalt.
